Her furry white coat, black tights, chunky moto boots, pigtails, and dark vampy lip were nothing short of '90s bliss. Perry even wore a gold choker necklace. Talk about flashback central! On any other celeb, we might be cautious of the over-the-top grunge look, but somehow Perry nails it. We'd venture to say even Courtney Love would be proud.
